Today many in our society claim to have no interest or belief in religion and readily dismiss the idea of an afterlife. Of course, opinion on the matter may shift a bit with age or illness, as one’s apparent mortality becomes more obvious. Almost all people will at one point ponder the question: “What happens when I die?”
We have examples where blatantly incorrect statements are made even though scientifically measured data points in the opposite direction. When a person, knowledgeable in their field, today states a fact based upon measurement, if his fact differs from the popular narrative, the individual is vilified. Far to many are afraid to speak up on matters where the truth is evident, because the facts don't match the popular narrative.
Failure to heed warnings has led mankind to experience a near continuous litany of needless suffering and sorrow over the millennia. Have you ever ignored a warning, one that if heeded would have saved you much grief?
